DragonFly hangs on laptop
I'm trying to get DragonFly to run on an aged 400MHz Celeron Laptop
(Gericom Overdose 2). It hangs somewhere in the clock calibration code.
When I boot from the live CD (GCC2 snapshot from March 23 as well as
homemade ISOs from today) it sometimes hangs at (from boot -v):
Calibrating clock(s) ...
I haven't checked where exactly it hangs in this case.
Sometimes it will advance a bit further and give me:
Calibrating clock(s) ... TSC clock: 399366840 Hz, i8254 clock: 1193077 Hz
CLK_USE_I8254_CALIBRATION not specified - using default frequency
CLK_USE_TSC_CALIBRATION not specified - using old calibration method
Some printfs I inserted showed that it advances up to the DELAY(1000000)
in startrtclock() from where it won't return. old_tsc is somewhere in
between 1400000000 and 1700000000.
I haven't tried CLK_USE_I8254_CALIBRATION or CLK_USE_TSC_CALIBRATION in
my kernel config yet (don't know if it would help and no more blank CDs
Which one of the two scenarios happens seems to be random. FreeBSD 4.10
and 6 also hang at early stages on this machine. Linux and Windoze come
up nicely though.
